Vegetação, ILuminação natural, Simulação da luz naturalResumo
Árvores se constituem em elementos complexos quando observadas em relação à transmissão, reflexão e dispersão da luz. Variáveis como altura, geometria e forma da copa, das folhas, do tronco e galhos, bem como, cor e transparência impactam na trajetória da luz. Assim, esse artigo apresenta resultados de uma investigação conduzida com o objetivo de mensurar e analisar o impacto da vegetação na iluminação natural de ambientes internos. O método proposto consiste em utilizar uma espécie arbórea em escala reduzida (bonsai), simulando uma vegetação em tamanho real, em conjunto com ambientes internos, em escala reduzida, e medições da iluminância interna sob céu real. Os resultados obtidos demonstram que a obstrução causada pela árvore pode reduzir expressivamente (68%) as iluminâncias internas, por outro lado, a vegetação contribuiu para a uniformidade nos níveis da iluminação.
